Certainly there's a place for a chicken and egg argument.
I mean, toy makers could be saying "Female action figures just don't sell" because they're unwilling to try.
But it also could be that toy makers don't make female action figures because they really don't sell.
I can see that argument being made, but Hasbro and Mattle marketing are actually pretty tightly run ships if what I've heard is true and I have a hard time seeing them not doing market analysis due diligence for the sake of supporting the patriarchy. I could be wrong, but having worked for consumer goods clients, the amount of work and focus groups and all that when launching an NPI would put most companies out of business.
